mav_callbackMouseSet, mav_callbackMouseExec

## Summary

Mouse callback management.

## Syntax

void mav_callbackMouseSet(int but, MAV_window *w, MAV_class *c, MAV_callbackMouseFn fn);

int mav_callbackMouseExec(int but, MAV_window *w, MAV_object *o, MAV_mouseEvent *me);

## Description

mav_callbackMouseSet sets the callback function for mouse events generated by button `but`, for object class `c` in window `w`, to be `fn`.

When a mouse event is detected by mav_eventsCheck, and a mouse callback has been registered for that class of object, the system calls mav_callbackMouseExec to execute `fn`, passing it the mouse event data `me`.
